Blood Glucose Levels and Obesity

• Regulation of Blood Glucose Levels

  • All cells in the body need energy in the form of glucose from the food we eat.

  • As the body needs a continuous supply of glucose and we are not constantly eating the body employs a system of negative feedback control.

  • This means there is always glucose available in the bloodstream.
• Adrenaline

  • In order for this to happen the adrenal gland secrete the hormone

  adrenaline.

  • This hormone overrides the negative feedback control that normally takes place.

  • It does this by:

  1. Stimulating glucagon secretion
  2. Inhibiting the secretion of insulin

  • Once the event is over the adrenaline level is reduced back to a minimum and blood glucose levels are returned to normal through negative feedback control.
